I think every administration does this sort of thing. Nothing unusual about Biden doing it. If it had never happened before, where on earth would a clown like Biden get the idea?

I have never believed a president's "economic policies" have much effect on the economy during his term. Government policy over the long run impacts the economy of course. But W Bush didn't "destroy the economy" in 2008, and Obama didn't save it, and Trump didn't repair it after Obama. Had Trump been reelected, the current economy is the one we would have now, and Trump would be savaged for it.

When it comes to the economy presidents are either lucky or unlucky. Smart doesn't much matter.
